Weapon Proficiency

Diminished Spellcasting

An iron-ring striker has one fewer spell slot of each level than a regular magus. If this reduces his number of spell slots of a particular level to 0, he can cast spells of that level only if his Intelligence allows bonus spells of that level.

Unarmed Spellstrike (Su)

An iron-ring striker gains the magus spellstrike class feature. However, an iron-ring striker can deliver spells with spellstrike with only unarmed strikes.

This alters spellstrike.

Unarmed Strike

An iron-ring striker gains Improved Unarmed Strike as a bonus feat. He deals unarmed strike damage as per a monk of his level. For the purpose of determining damage, these levels stack with levels from any other class that grants increased damage to unarmed strikes.

Empower Combat (Su)

At 7th level, an iron-ring striker learns to use magic to grant himself the power of a larger creature. As a standard action, he can expend one non-cantrip prepared magus spell to treat his size as if it were larger for the purposes of determining the size modifier to his CMB and CMD, as well as which creatures he can affect with combat maneuvers. For every level of the spell he sacrifices, his effective size increases by one step, up to a maximum of Colossal. For every two effective size increments he increases, he gains a +2 size bonus to Strength, to a maximum of +6.

This does not change the iron-ring striker’s actual size. This effect lasts for 1 minute per level of the spell sacrificed.

This replaces medium armor and heavy armor.

Spell Maneuvers (Su)

At 7th level, as long as an iron-ring striker is wearing light armor or no armor, he can use his unarmed spellstrike ability as part of a combat maneuver check to bull rush, disarm, sunder, or trip an opponent.
